Injection Molding
Pengertian Sejarah
Adalah metode pembentukan
material termoplastik dimana
material yang meleleh karena
pemanasan diinjeksikan oleh
plunger e dalam cetakan yang
didinginkan oleh air sehingga
mengeras
 Dipatenkan pertama kali
tahun 1872 di USA untuk
memproses celluloid
 Tahun 1920-an di Jerman mulai
dikembangkan mc injection
molding manual
 Tahun 1930-an mulai
dikembangkan secara
hidraulik
 Tahun 1950-an mulai
menggunakan relay dan timer
untuk proses injeksnya
Komponen Utama:
1. Unit Injeksi
Berfungsi
melelehkan plastik
2. Mold
Berfungsi mencetak
dan mendinginkan
3. Unit Pencekam
Berfungsi mencekam
mold pada saat
penginjeksian
material
Contoh mc Injection molding
DAHULU
SEKARANG
Jenis-jenis Mc Injection
-Berdasarkan metode pencekaman
cetakan
a. Pencekam toggle
b. Pencekam hidraulik
-Berdasar tonase:
a. Kisaran mulai dari 5 ton untuk
menghasilkan produk seberat
10 gram
b. Kisaran sampai 5000 ton
untuk menghasilkan produk
seberat 50 kg
-Berdasarkan proses pelelehan biji
plastik
a. Single-stage plunger
b. Two-stage screw-plunger
c. Single-stage reciprocating-
screw
Proses Injeksi Plastik
1. Mold CLOSE
2. Fill Injection
3. Holding Injection
4. Charging and Cooling
5. Mold Open
Hasil Produk
a) Kapasitas 1kg
b) Kapasitas 1Ltr
c) Kapasitas 4Ltr
e) Kapasitas 5Ltr
f) Kapasitas 10Ltr
g) Kapasitas 15Ltr
h) Kapasitas 20Ltr
Analisis SWOT terhadap bagian
work injection
 Strenght
 Memiliki variasi mesin
 Standar internasional
 Mencapai target omset
 Mudah dalam promosi
 Mudah dimaintenance
karena sudah banyak
teknisinya
 SDM loyalitas,flexible,jujur
 Bangkitnya kepercayaan
customer
 Weakness
 Sulit mencari bahan baku di
pasaran
 Produk yang diproduksi
work injection juga
diproduki perusahaan lain
 Hanya bisa membuat produk
berbahan plastik
 Jarang memberi diskon
 Promosi belum memakai
iklan
 Pengelolaan belum
sepenuhnya mandiri
 Jumlah customer perorangan
belum banyak
Analisis SWOT terhadap bagian
work injection
 Opportunities
 Kerjasama peningkatan
produk
 Kontrak dengan para
pelanggan
 Perkenalan melalui jasa
iklan
 Kesempatan pemasaran
melalui pelanggan yang
menyebar
 Threats
 Banyaknya kesalahan
produksi
 Para pesaing
menawarkan produk
yang sama dengan harga
lebih murah
 Dampak krisis ekonomi
global
 Ancaman dari
perusahaan lain yang
sejenis
Kesimpulan
Kemajuan teknologi adalah sesuatu yang tidak
bisa kita hindari dalam kehidupan ini, karena
kemajuan teknologi akan berjalan sesuai dengan
kemajuan ilmu pengetahuan. Begitupun dengan mc
injection molding, seiring berjalannya waktu,
penggunaannya jadi semakin mudah dan praktis.
Sekian danTerimaKasih
